Dry the lams, put on a sizing coat before glue up and mate the surfaces well, and that stuff is VERY strong.

Hermann, TB is Tite-Bond glue. It is a common yellow carpenters glue. You will see it posted as TBI, TBII, and TBIII. The first two are water resistant after drying and TBIII is water proof after drying

The strength of TB is just amazing if your surfaces mate reasonably well-if not you will need to adjust them, or mix up some epoxy.

A friend brought a BBO blank he bought to my shop a few weeks ago. We carefully tillered it and just had to drop about 10 lbs of poundage off to finish the bow. He was dropping poundage when the glued on handle failed all the way back to the spliced limbs. The splice came apart and the bow was toast. The splice was pretty short, about half as long as I make them, the handle failure started the bows destruction.

Everything appeared to have been glued with TB.

I have had TB failures early on in my bowmaking journey so I switched to Urac. My early TB failures were probably the result of my poorly constructed bows rather than any problem with the glue itself.
